Ronaldo ‘ll ruin you, Zidane warns Man City

French legend Zidane inherited a fractured dressing room from Rafa Benitez when the Spaniard got the axe in January. While Gareth Bale was sad to see the former Liverpool and now Newcastle boss go, Ronaldo’s relationship with Benitez had all but broken down.

Ronaldo, 31, failed to score in Real’s first eight big matches of the season, the win at Athletic Bilbao, the draw at Atletico Madrid, both clashes against PSG, the loss in Seville, the home loss to Barcelona, the loss at Villarreal, and the draw at Valencia.

It fuelled rumours the Portuguese striker would be on his way this summer, with PSG desperate to lure him to Ligue 1 and Manchester United fans dreaming of an Old Trafford return.

And Zidane told Manuel Pellegrini and his Etihad troops the star of the Real squad is once again in the frame of mind to show he is the finest on the planet.

Ronaldo’s hat-trick in the quarter-final comeback triumph over Wolfsburg took him to 16 goals in the Champions League this season — just one behind the record he set as Real completed their tenth triumph in 2014.

He has now scored nine in the six most important matches since Zidane’s appointment in January.

In what appeared a deliberate sideswipe at Benitez’s handling of Ronaldo, Zidane said: “Cristiano has always been like this with me.

“There may have been moments where he didn’t score but you never have to worry about Cristiano. He is very happy and very comfortable with everyone here not just with me.
